Is The rational Male a good book to read as your first?

I’m in the process of going monk mode while I finally have the fucking opportunity to work on myself and I’m look for a good book to read while I self improve. Also I’m not trying to ready anything about female nature..I just wanna get my shit together on focus on myself.

P.S. I already bought TRM But it’s never to late to get more rp/self help books.
